background and aim: tinnitus is an auditory phantom percept in the absence of any objective physical sound source. although advances have been made in its treatment, there is very low percent of patients that report an elimination of their tinnitus. a novel approach using noninv­asive neuromodulation has emerged as an inter­esting and promising modality for tinnitus relief. our aim in this revi...

This study examines patterns of auditory cortical activity elicited by single-pulse cochlear implant stimuli that vary in electrode configuration, cochlear place of stimulation, and stimulus level. Recordings were made from the primary auditory cortex (area A1) of ketamine-anesthetized guinea pigs. The spatiotemporal pattern of neural spike activity was measured simultaneously across 16 cortica...

Ideally, interference in neural measurements due to signals from nearby muscles can be completely eliminated with the use of tripolar nerve cuff electrodes, in combination with appropriate amplifier schemes. In practice the cuff departs from its ideal model leading to cuff imbalance. As a result, the output nerve signal of such amplifiers has been widely reported to be degraded by interference,...

The problem of nonlinear self-organization of perturbations in differentially rotating, nonuniform, gravitating systems is studied. Two types of stationary nonlinear solutions, in the form of tripolar vortices and vortex chains of gravitational potential and density, dependent on the spatial profiles of the basic state quantities, are found. They propagate with a constant velocity perpendicular...

a b s t r a c tthe applications of neurophysiological therapy techniques range far and few in the realm of modern day medicine. however, the concept of electromagnetic stimulation, the basis for many noninvasive brain stimulation (nibs) techniques today, has been of interest to the scientific community since the late nineteenth century. recently, transcranial direct current stimulation (tdcs) a...

During bipolar mitosis a pair of centrioles is distributed to each cell but the activities of the two centrioles within the pair are not equivalent. The parent is normally surrounded by a cloud of pericentriolar material that serves as a microtubule-organizing center. The daughter does not become associated with pericentriolar material until it becomes a parent in the next cell cycle (Rieder, C...
